SEED-'DROPPING ATTACHMENT FOR CHECK-ROW COHN-PLANTERS.

SPECIFICATION forming part ofV Letters Patent No. 264,550, datedSeptember '19, 1882,

To all 'whom 'tt may concern 4 clear, and exact description.

Reference is to be had tothe accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures. A

Figure 1 is a plan view of our improvement. Fig. 2 is a rear elevationof the sainef Fig. 3 is a side elevation of the driving-wheel.

Theobject of this invention is to facilitate .the planting of corn inaccurate check-rows.

The invention consists in a seed-dropping attachment for corn-planters,constructed as will be hereinafter fully described.

A represents a frame, about three feet long and about ten or eleveninches high, and which is designed to be attached to the tongue B or theframe of the planter a little in front ofthe seed-boxes O. l i

In bearings attached to the forward sides of the ends of the frame A'revolves a rod,D, to the outer end of which is attached a spokewheel,E, abouttwenty-nineinches in diameter. The spokes of .the wheel E enterthe ground,

l so that the said wheel will be turned as the machine is drawn forward.

To the inner end of the rod D is attached a gear-wheel, F, about eightinches in diameter, the teeth of which mesh into the teeth of thel smallgear-wheelG. The gear-wheel Gis about two inches in diameter, and shouldmake exactly four revolutions while the gearwheel F makes one.

To the small gear-wheel G is attached or with` it is rigidly connectedachain-wheel, vH, around which passes an endless chain,I. The endless'chain I also Apasses around a chain-wheel, J,

Appncanon nieu May 1, 1882. (No moda.)

To a link ofthe chain I is attached a finger or hook, K, which, as itpasses along the npper part of the frame A, strikes against an arm, L,attached to the upper part of the upright shaft M, and turns the saidshaft in one direction. As the finger or hook K passes back ,along thelower part of the frame A it strikes agansta second arm, N ,attached tothe lower part of the shaft M, and turns the said shaft in the otherdirection. Ihe ends of the shaft M are journaled to brackets, O,attached to the top and bottom bars ofthe frame. A.

To the shalt M is attached a rearwardly-projecting arm, P, the outer endof which works in a band, Q. attached to the forked end ofthe pitm'an R.The outer end of the pitman R is pi voted to the seed-dropping slide Sof the planter. 1

With this construction two hills will be dropped at'eachhalf-revolutionof the drivewheel E, so that the yhills will be about three feet nineinches apart.

Upon'the outer ends ot' two opposite spokes of the drive-wheel E aresecured cross-heads T, to mark the line of the cross-rows, which markswill serve as a guide to the driver in thel return crossing, so" that hecan plant the h'eld in accurate cross-rows.

We are aware that seed-dropping attachments for planting corn iucheck-rows, having a spoke drive-wheel, beveled gears, and afinger-chain for tripping the seed-valve similar to ours are not new,and we do not claim this, broadly, as our invention; but

What we claim is- The combination, with the wheel E, shaft l), beveledgears'F G, chain-wheels H J, chain l, and hook K, ot' the verticalrock-shaft M, the arms L N thereon, the arni P, and the pitman R,operating the planter slide or gate, as shown and described.
